In the past, when a property owner chose to install a slate roof they had to be prepared to install the structural support needed to hold up the extra weight of the slate. Now, thanks to our patented interlayment system, a SlateTec® roof requires 40% less slate than a traditional installation! This cuts the overall weight per square foot down to less than six pounds, which means a house that was originally roofed with cedar shakes or asphalt shingles typically will not need any additional structural work. Not to mention, a SlateTec roof offers the traditional slate roof aesthetics. You can choose from a wide selection of slate colors from around the world in a variety of widths and textures to create the perfect look for your home.
